Corsair RM750 750W Power Supply Review

We have all read about Corsair power supplies and it is quite likely that many [H]'ers have one in their computer case right now. Today we are looking at Corsair's newest RM series power supply rated at 750 watts. The RM is built, "fully modular and optimized for silence and high efficiency." Let's see how it handles our grueling power tests.

Introduction

Corsair is known in enthusiast circles as a premier supplier of high performance memory and has risen to become one of the most talked about power supply brands around. Corsair was able to establish such presence through rigorous design standards, excellent support, and the use of quality OEM’s such as Seasonic and CWT. Since its entrance into the PSU field, Corsair has established a number of lines of power supplies to address and overlap just about every market segment with its VS, GS, CX, VX, TX, RM, HX, and AX lines as well as those product lines revisions and subdivisions. Today, Corsair has for us another new line of power supplies, the RM series, of which we will be looking at the RM750 model. This power supply is produced by Chicony/Hipro.

Chicony Power Technology Co is the power supply manufacturing division of the Chicony Electronics group. It was founded in 1983 and it is headquartered in Taiwan. Chicony provides a wide range of electronic manufacturing, OEM/ODM services, and retail management. Some of its more familiar ventures, to most users anyway, are Clevo, Hipro, and BuyNow. However, while Chicony’s Hipro division has been providing power supplies for major OEMs like Dell and HP for some time, its production of units for the consumer SMPS market in North America is a bit more limited than what we have seen from some of the other large power supply producing conglomerates. Indeed, Corsair is bringing us the first product from Chicony that we have reviewed to date.

The Harbor is Getting a Little Busy

Today, we are looking at yet another new power supply line from Corsair. One of the things we have noticed over the last few years is just how very prolific Corsair has been with line after line after line of power supplies. As it stands today, the RM750 will be the 4th 750W power supply we have seen from Corsair and it is one of three still available currently. As such, while Corsair is certainly going to be facing some competition from other brands, the RM750 is going to have a lot of internal competition. This internal competition certainly leaves us with the interesting prospect of seeing how much this unit can distance itself from the other 750W units that we have reviewed that Corsair still has on the market. Before moving on though, what does Corsair have to say about this unit?

The Corsair RM750 is fully modular and optimized for silence and high efficiency. It’s built with low-noise capacitors and transformers, and Zero RPM Fan Mode ensures that the fan doesn’t even spin until the power supply is under heavy load. And with a fan that’s custom-designed for low noise operation, it’s whisper-quiet even when it’s pushed hard.

80 PLUS Gold rated efficiency saves you money on your power bill, and the low-profile black cables are fully modular, so you can enjoy fast, neat builds. And, like all Corsair power supplies, the RM750 is built with high-quality components and is guaranteed to deliver clean, stable, continuous power. Want even more? Connect it to your Corsair Link system (available separately) and you can even monitor fan speed and +12V current directly from your desktop.

Moving on let’s see what we can expect when a user purchases the Corsair RM750 supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
